A self-intersecting rod is a rod that passes through the triangle formed by three other rods.
The solution I have in mind works best with the new longer bars,
because there is more space, but is completely build-able using classic Geomag.
It does not involve panels, and uses fewer than thirty rods.
As this is the first post to the challenges group we have no guidelines yet, so I'll propose some:
- Challenge name - of the form Cdate-handle, so that it can be referred to easily
- Challenge solution should be posted 1 week after the initial post
- Threaded keep discussion about a challenge all on the same thread
Hint: In the bad old days before panels you could stabilize square faces with
triangles making pyramids. The obvious thing to do is to orient the apex of the pyramid outwards.
But what if you pushed the spike inside?
